Application tiled October i9. 1595.

To all whom, [t muy concern:

Be it known that l, DANIEL Arret., a citizen of the United States, residing at Cleveland, county of Cuyahoga, and State of Ohio,

have invented certain new and usf'nt illll provements in Paper Bags, fulfy described l and represented in the foll 1VlwrroplltflOll and the accompanying4 am UigS, Ollllllg a part of the same.

This invention relates,'generall ,f, to that@ Class 0f paper bags which are made from a single piece of paper, which is folded trans i wersely upon itsel f and united at its edges, so as to form a bag having two side seams and a i seamless bottom. The invention relates par tieularly, however,to a bag of this class which is provided with what is known in the art as a Satchel-bottom.

The bags constructed according to the present invention maybe made from a continuous web or from detached sheets or blanks, the l same Vas is the case with most of the ordinary forms of paper bags.

In carrying on the practical manufacture of bags according to the presentinvention it will usually, however, be found most desirable to employ detached blanks which have been previously cut to the proper form. The operation of making a bag from such a blank is l, therefore illustrated in the present ease.

As a full understanding of the construction of the bag can be best imparted by a detailed i description of the manner in which the blank is treated in forming it, such description will l now be given, reference being had to the aecompanying drawings, in which- Figure 1 is aview of a portion of a blank of suitable form for making a bag according to y the present invention, the dotted lilies indil 4o eating the lines upon which the blank is folded in the formation of the bag. elusive, illustrate the various mation ofthe bag. Figs. 7 and 8 are views of i the opposite sides of the completed bag. Fig. l

9 is a perspective view of the bottom of the bag when distended, and Fig. 10 is an inside t view of the same.

Referring to said figures, it is to be understood that the sheet or blank, apart of which is shown in Fig. 1, is of rectangular form, and of suitable dimensions to form a bag of the from the edges to a point Figs. 2 to 6, in steps in the fori coincide Serial No. 180.21113. (No model l desired Size and proportions. Preliminary to the {0h/Ling the blank is provided at or near the middle of its length and upon opposite sides with transverse ents 18, which extend inward near the edge of that portion of the blank which forms the bottom of the completed bag, and with longitudinal slits 19, which intersect the ends of the cuts 18, and are of a length about equal to the width of the bottom of the completed bag. These cuts and slits 1S 19 serve to form free portions a a and b b at the opposite sides of the blank, the purpose of which will hereinafter appear. The blank is also provided at a suitable distance to one side ofthe cuts 18 with two short f cuts,17,whieh extend inward a distance equal,

or about equal, to one-half of the lap ot' the paper in forming the side seams, and serve to form free side portions or lips, g, at one end of the blank.

In addition to the lcuts and slits specified, the blank may and preferably will be creased i upon the dotted linesindicatethto aid in making the several folds necessaryin the formation ofthe bag.

In making a bag from a blank thus formed the t'ree portions g are first lfolded inward on i the lines 7 10, after which the blank is folded transversely on the line 9 9, so as to bring the portion A, which forms one side of the bag, over onto the portion C, which vforms the bottom of the bag, and the portion B, which forms the other side of the bag, as shown in Fig. 2. This being done, one edge of the portion A is folded inward on the line 11 11, which at the same time forms diagonal folds on the lines 7 11 and brings the free portion a and the portion c, which lies between the portion a and the eut 17, into the position shown in Fig. 2, thereby causing the portion a to partly overlap the portion b, and causing the line 9 l1 to with the line 5 11. The edge of the portion A is then folded back on the line 11 11 to its original position, thus folding the portion c upon the line 9 11, and bringing the portion o on top of the portion a, and both the portions a c beneath the edge of the portion A, as shown in Fig. 3. The other edge ner. It is first folded inward on the line 11 l 11, thus making diagonal folds on the lines 7 l1 at the other side of the blank, and bringing the portions a c at that side of the blank to the position shown in Fig. 3, after which it is folded back to its original position, thus 5 bringing the portions a c at that edge of the blank beneath the edge of the portion A. It will of course be understood that both edges of the portion A may be folded inward and then outward simultaneously, or that the Second edge may be folded inward before lthe first is foldedy back to its original position. After 'fhportions a c upon both sides of the blank have been folded under the-edges of the por- LPIQFIA, as just described. the ,side portion, A, w is raised up trom the portion B, and is foldedy Ont-Ward 0n the\:ir.e 7 '7, asgho'wu in Fig, 4, The portion A'and thejbotto'm Borgio", C are then foldedback onthe 'line 8 8, as showh in Fig. 5, thus causing the line 7 7 to coincide 2o with the line 6 6.and'nt thesame time bringing the free portions @von top of the free p0rtions a, and causing the--b0tto|n portion, C, to overlap the side portion, A,'f`or one-half its width,as shown in Fig. 5. After this is done 25 the free portions a and the edges of the bot tom portion, C, are folded inward on the coinciding lines 5 11 and 9 1l, thereby removing the portions a from beneath the portions b and laying the former over onto the bottom por- 3o tion C.

In folding the edges of the portion C over on the lines 5 ll the portionsb will be drawn inward so as to form diagonal folds upon the lines 4 5, and also upon the lines 2 7. and per- 35 mit the portionsb to be laid down directly on top of the portions a, as shown in Fig. 6. After this has been done the side portions, A B, are folded Over together on coinciding lines 6 6 and 7 7, thereby carrying the bottom p0r- `4o tion, C, over s0 that it overlaps the side B, as f shown in Fig. 8, and at the same time unfolding the folds upon the lines 4 6, yand forming diagonal folds on the lines 3 6, and causing the narrow marginal portions h of the side B to be folded over on the lines 6 12'onto the 45 The overlapping plies or points formed by the A5o i ,y

In testimony whereof I have hereunto set myl hand in the presence of two subscribing witnesses.
